Pink Quartz (likely Rose Quartz or Pink Feldspar)
Quartz var. Rose Quartz (Silicon Dioxide) · Semi-Precious Gemstone / Decorative Stone
Crystal System
Trigonal; typically occurs in massive form or as water-worn pebbles in secondary deposits.
Mineral Group
Silicates (Tectosilicate subgroup)
Chemical Formula
SiO2 (often with trace amounts of Titanium, Iron, or Manganese)
Formation Process
Primarily Igneous; forms in late-stage magma crystallization within pegmatites, later weathered and rounded by water transport.
About This Crystal
A small, rounded, water-worn pebble approximately 1.5 cm in length. It displays a dusty rose-pink to peach-pink hue with an opaque to translucent transparency and a waxy to dull vitreous luster.
Physical Characteristics
Color: Pink; Streak: White; Cleavage: None; Fracture: Conchoidal (observable on chips); Specific Gravity: 2.65; Fluorescence: Usually inert or weak purple under UV.
Optical Properties
Refractive Index: 1.544–1.553; Birefringence: 0.009; Optically Uniaxial (+); typically no pleochroism in massive forms.
Hardness & Durability
Origin Region
Commonly found in Brazil, Madagascar, South Africa, and the USA (South Dakota). Often found in alluvial river deposits as rounded pebbles.
Hardness & Durability
Mohs Hardness: 7; Toughness: Good; Highly durable for jewelry and handling, resistant to most household chemicals.
Care & Maintenance
Clean with warm soapy water. Generally stable, but prolonged exposure to direct sunlight may cause some pink quartz varieties to fade over time.
Rarity & Value
Common; Value is generally low for small tumbled specimens, determined by color intensity and size.
Special Characteristics
This specimen appears to be a 'river stone' or 'alluvial pebble,' showing natural mechanical weathering (rounding) from water transport.
Lore & History
Historically used in ornaments since 7000 BC. Traditionally associated with the Heart Chakra, symbolizing unconditional love, peace, and emotional healing in folk traditions.
